TO ALL WHOM IT. M-AYSCONGER'N: I i

Be it known that I, CORNELIUS CALLAGHN, of'Great .Britaini'residin et Boston, in the county of Su''olk', and State of Massachusetts, have invented-Improvements in Brooch-Loading Shot-Guns;'a,nd I'do'hereby declarethat the following, taken in connection with the drawings whichl accompany and form -po'rt of this specificati-on, is a. description' of niy invention sufficient to enable those skilled'in the crtto practise it.

The invention relates to the construction ofibreech-loading shot-guns, particularly of-thnt class in which the-Charge is wholly contained withinal cylindricaltube or cuse, iitted` to slide intoaud out from the rem gf' the barrel, and to receive suceessivefcharges olfvpowder and shot. l v -V The improvement consists primarily in combining with the two barrels -of a double-bcrrelled gun, two

broechblocks, each hung at its opposite ends to the frame, and swinging outwardly, for insertion-of the charged case, or the vithdrawelof theempty shell, the two 'breech-blocks' being locked'when closed) to a central rib or bridge connecting the'borrels to the rear part of the metal frame, andesoh swinging-block piece containing the lock forexploding-the cap or the-cartriilgeof the barrel inline' with it.' v l The invention also consists inlsoconstruct'ing the crm that the barrels, frame, and locks areso connected 'that they ere capable of removal from and of connection with-the stock; as onepiece, or in combining the locks directly with'and so as to be removed with the barrels. I l

The drawings' represent those parts of on armv directly embodyingmy invention.

A'shows a side elevation, und B a plan of' the breech-block or blocks und frame, and the adjacent `parts of' the barrels and stock. p C, u longitudinal vertical section through one ofthe hammers., Dya plan,"sho`wing the breech-blocks -as thrown out, and one of the cortridgeor chargeontaining tubes 'as nearly withdrawn fi'einp the barrel. E, an end view of the barrels' and'framegfshowing-one breech-block as thrown ont.` apdenotes the stock, Z5 b the barrels, c the metal frame supporting th-ebarrels and the'lock-mechanism. :From the rear piece d of this frame to the borrel b a. vertical central .rib,-e, runs, ondl-on'ec'clli side of this ribthandinline withthq barrels, are two swinging breechblo'oksf, eeclrhutugriby journalepin's glitt its opposite ends',A and swinging out-i Wardly or transversely to the barrels, VAas seenst Deuil E. This centrally-:rib e is in heght Hush with the upper surface `of the breech-blocks, and of such thickness -and soliclity, ondesogiirmly secured lnsjpnrt'tif iihifl'D-IQQ,

io be of great importoncein resisting the recoil upon the dischnrgd-o'tl-.the gun.v Without'su'ch rib the other parts of the frame would be altogether -insucient to, resist this recoil, becauseof their comparatively lighter structure und becaus'ethey are not in the line of href' -n'or would that part of the breech-blocks which is journblled in the frame be suilcienttopresist the'recoih for the reason that it is located in too' low a plane and much below the line of re, while the breech-blocksl themselves fail toA resist the lfrecoil, because they form no strengthening part between thefront and rear oi' the frame, und they ore n ot fastenedA to but. are merely laid within the frame, for the specific purpose of being inserted and removed with-fneility'w'ithout the need of sci'evrsr4 This central rib is not designed or used merely, for the purposieof nording-aconvenient means for locking or securing in position the two breechblocks, when clse1l, for these blocks could readily be caused to llock to each other, and by the sume character of device which I now use to'lo'ckythem to the rib; b'ut I could not dispense with the-rib without materially damn-ging the'value and eiicieney of my'gun in .thef'oth'er impcrtant'particulars nbore statedg' nud, moreover, ii' dispensed with, it wouldbe necessary to uiake'the stock in two pieces `in order to ins'urethe't strength 4which metal clone cangive, and which would iu such case be required underneath the` i freine. When closed, euch breech-blockts securelybetween the barrel c'fl the frame-'piece d, and closes firmly against the head of the charge-containing tube inserted into the berreh-thetwo blocks being locked iu closed position by a button or boltJi, which, upon being turned, shoots into two notches or rcessesfz', in the opposite breech-blocks,) or by any other suitable Incensi' When eitherbreeelr-block is thrown out it discloses and opens the barrel in line with it, and permits the insertionor removal of the cartridge or charge-containing tube 7d This tube c is preferably formed of thin sheet metal, is :uncle-telit closely into the barrel, ondis of sizorsucient to receive a. maximum charge of powder und shot. At its rear or olosedend it has a cone orfnipplell,

for receiving the pcrcussiongcop, this cone `being lined to und leading into the tube, as 'shown'.ot C, and entering insist, m, in the rearend of the barrel, v(whe n the charged tube is slid into the' barreh) coming directly 'under or in position to receive the b'low from' the striking-facelof -tlieiiaminer u.' Each hammer, muis hung to or in the breech-block on its srie of the gun, and the block also contains the other mechanism of the lock, as seen' at C, the sere o being pressed under the teeth or notohesiin the hammer or cock (when the hammer is raisedto' full. er 'half cock) by the sere spring p, the sere being tripped by a lifter, q, acted upon by the trigger r, and

the hammer being thrown down by its spring s, all as willbe readily umlerstood.v

As before stated,rtl1e barrels, breech-frame, andv breech-blocks have a. permanentzconnection, together or with reference to the stock a, a tongue, t, projecting into a slot in the stock-piece, and n. key, ze, locking the barrels down to the stock. By removing this key, raising the barrels and moving them forward, the borrels, breech-frame, and swinging blocks, and with the blocks the percussion-locks, are all removed from the stock as one piece, this arrangement, for the purposes of constr'uotion, of repair, and of-pockin-g, being of material advantage.

The bearings in the frame for the reception of the journals of the swinging breeohfblocks are open at the.

bottom, so that when the frame is removed-.from the stock and the blocks released from the rib, these blocks may at once be removed by simply taking their journals from these op'en bearings or sockets.

I claim the combination with a central rib, substantially such as described,v of ,t'wo breech-blocks swinging 4outwardly therefrom.

Also, the combination, with a. removable frame, of` the breech-blocks, substantially as described, so that vwhen the frame is removed from the stock and the blocks released from the rib, the blocks are free to be removed from the frame, substantially as described.
